ac1015e3c4 Trimmed vtables of trailing zeroes.
This is something the format supports, but none of the builders
were doing. Can save 10-20% on FlatBuffer binary size!

Also fixed the Go tests.

Tested: on Linux.

1e7310e6cd Fix CreateString with already-encoded string or bytearray in Python 2.7.
There was no way to pass an already-encoded string to 
`builder.CreateString` in Python 2.7:

- Passing a `bytearray` raised a TypeError because `bytearray` was not
  recognized as an instance of `compat.binary_type`.
- Passing a utf-8 encoded `str` would cause the string to be
  double-encoded, because `compat.string_types = (basestring,)` and
  `basestring` is the base class of `str` and `unicode`, so the logic
  would never reach the `elif isinstance(s, compat.binary_type)` case.
- Converting a utf-8 encoded bytearray to `bytes` like
  `builder.CreateString(bytes(encoded_string))` does not work because
  in Python 2.7, bytes is just an alias for `str` so it behaves as
  above.

This change allows either `bytes` or `bytearray` as an already-encoded
string to be passed to `CreateString` in versions of Python that support
`bytearray`, and falls back to `str` in older versions.

In Python 2, it restricts unencoded string types to `unicode`, so `str`
can be used as an encoded, binary representaiton.

69a31b807a Revamping the FlatBuffers docs.
Adding an API reference for the supported languages.

General docs cleanup, including a new `tutorial` section that
supports all of the supported languages.

Added samples for each supported language to mirror the new
tutorial page.

Cleaned up all the links by making them `@ref` style links,
instead of referencing the names of the generated `.html` files.

Removed all generated files that were unnecessarily committed.

Also fixed the C# tests (two were failing due to a missing file).

Bug: b/25801305

Tested: Tested all samples on Ubuntu, Mac, and Android. Docs were
generated using doxygen and viewed on Chrome.

af23683311 [BUG FIX] [MINOR] Fix encoding with unicode characters.
When passing a unicode string to builder.CreateString, the
default encoding assumed all characters can be encoded
using ascii. Added a fix so a user can specify the
encoding and how to handle errors when creating strings.

3232727ace Python: Improve Builder user interface.
+ Add state to the Builder object to track if we are inside a table,
  and if we are finished building the buffer.
+ Use this data to check that a buffer is being built correctly.
+ Raise an exception if a buffer is not being built correctly.
+ Test that the exceptions happen as expected.

Based on d236dea.

d9db48257b Add self.assertNotNested() in CreateString
And also add a test case.
If you try to nest CreateString you will get a clear exception.

48dfc69ee6 Port FlatBuffers to Python.
Implement code generation and self-contained runtime library for Python.

The test suite verifies:
  - Correctness of generated Python code by comparing output to that of
    the other language ports.
  - The exact bytes in the Builder buffer during many scenarios.
  - Vtable deduplication correctness.
  - Edge cases for table construction, via a fuzzer derived from the Go
    implementation.
  - All code is simultaneously valid in Python 2.6, 2.7, and 3.4.

The test suite includes benchmarks for:
  - Building 'gold' data.
  - Parsing 'gold' data.
  - Deduplicating vtables.

All tests pass on this author's system for the following Python
implementations:
  - CPython 2.6.7
  - CPython 2.7.8
  - CPython 3.4.2
  - PyPy 2.5.0 (CPython 2.7.8 compatible)
